摘要
地膜覆盖种植技术,经过几十年的应用,产生了严重的残膜污染危害,但现阶段对于保障我国农产品安全供应依然发挥着不可或缺的积极作用,故残膜污染防控不可回避。残膜污染防控技术措施主要有地膜减量化应用、降解膜替代普通聚乙烯地膜和残膜回收3种。阐述了我国农用地膜发展应用概况、覆膜种植积极作用、残膜污染危害及残膜污染防控技术措施,展望残膜污染防控技术,以期为残膜污染防控提供参考。
Plastic film covering planting technology has been applied for decades and residual plastic film has become a serious pollution hazard.Given its positive role in safe supply of agricultural products in China,plastic film mulch is indispensable and thus it is inevitable to prevent and control residual film pollution.At present,there are three main measures for prevention and control of residual film pollution,namely,reducing use of plastic-film mulch,replacing common polyethylene film with degradable ones,and recycling residual mulch film.Development and application of agricultural plastic film in China,positive effect of plastic film on planting,harm of residual film,and measures for prevention and control of residual film pollution were introduced.Prevention and control technology of residual film pollution was prospected,hoping to provide a reference in this respect.
